Fermentation Without oxygen, pyruvate is not metabolized by cellular respiration but undergoes a process of fermentation. Thepyruvate is not transported into the mitochondrion, but remains in the cytoplasm, where it is converted to wasteproducts that may be removed from the cell.ermentation Without oxygen, pyruvate is not metabolized by cellular respiration but undergoes a process of fermentation.

specific pathogens that are causing disease (B cells produce antibodies against bacteria or viruses in the extracellular. fluid, while T cells kill cells that have become infected). The immune system is closely tied to the lymphatic system, with B and T lymphocytes being found primarily within lymph nodes. Tonsils and the thymus gland are also. considered lymph organs and are involved in immunity. We often don't realize how effective the immune system is. until it fails or malfunctions, such as when the lymphocytes are attacked by HIV in an AIDS patient.
Best Answer: B lymphocytes or B cells secrete antibodies and act in humoral immunity. Humoral Immunity results in the production of antibodies that circulate around the body in blood and lymph (humors). Defends against: free bacteria and viruses.
